CLEVIS.

SPECIFICATION forming part of Letters Patent N 0. 703,060, dated June24, 1902.

Application filed September 25, 1901. Serial No. 76,558- No model.)

To (all whom it rncty concern:

Be it known that 1, WILLIAM M. GRISWOLD, a citizen of the United States,residing at Monroe, in the county of Randolph and State of WestVirginia, have invented a new and useful Glevis, of which the followingis a specification. v

This invention relates to a clevis adapted to be applied to the ends ofplows or other draft-beams; and the object of the same is to provide asimple and effective device of this class which is strong and durable inits construction and having adjustable means included therein of aparticular character for changing the line of draft and capable ofhaving any sort of rigging or draft devices applied thereto.

The invention consists in the construction and arrangement of theseveral parts, as will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a portion of a beam,showing the improved clevis attached thereto. Fig. 2 is a transversevertical section taken on the line 2 2, Fig. 1.

Similar numerals of reference are employed to indicate correspondingparts in'the views.

The numerals 1 and 2 designate upper and lower parallel bars forming theattaching means for the improved clevis and each having a rear eye 3 toreceive a securing-bolt 4:, which is headed at its upper end andscrewthreaded at its lower end for removably applying the same in amanner which will be readily understood. The front portions of the bars1 and 2 are connected by a verticallydisposed brace-bar 5, and extendingcentrally from said brace-bar is a horizontal partitionbar 6, having itsouter end in alinement with the ends of the bars 1 and 2, respectivelyabove and below the same, and thus providing slots 7 and 8. The slots 7and 8 are located in what may be termed the head of the clevis, whichstands in advance of the beam to which the clevis is applied. The bars 1are fitted over the upper and lower sides of the beam, with the brace 5bearing against the front end of the beam, the latter having a spur orspike 9, which enters the beam and assists in holding the clevis inimmovable applied position and prevents the head from moving laterallyin either direction. The bolt 1 is passed through the beam, as shown indotted lines in Fig. 1, as well as being placed in engagement with theeyes 3 of the bars 1 and 2, and when the bars are so attached it will beseen that the securement of the clevis is positive, and but one bolt isnecessary to hold the device in secured relation to the beam, therebyavoiding unnecessary mutilation of the latter and also providing meansfor quickly applying and removing the clevis.

Extending vertically through the projecting ends of the bars 1 and 2 andthe partitionbar 6 is a bolt 10,which is provided with a socketedwrench-head 1O at its upper end and screw-threaded at its lowerextremity to engage the lower bar in a removable manner. This bolt 10holds a clevis-block 11 in either one of the slots 7 or 8, the saidblock having flanges 12 and 13, respectively, at the lower portion ofone side and the upper portion of the opposite side to engage the oneside edge of the lower bar 2 and the one side edge of the partition 6 toprevent the said block from turning or moving out of a desired position.By means of a suitable bolt 14 a clevis-loop 15 is movably attached tothe block l1,and the rear edge 16 of said block is concaved, so

that an auxiliary ring (shown in dotted lines in Fig. 1) may movethereagainst and serve as an auxiliary device for attaching draftmechanism or parts of the latter. By detaching the bolt 10 the block 11may be moved into the upper slot 7 and secured, as shown, or the changemade at will from the upper slot to the lower slot to regulate the draftand, if the clevis be applied to a plowbeam, to so change the draft thateither a shallow'or deep cut may be made.

The advantages of the improved clevis are manifold, and in addition tothe strength, durability, and ease in attaching and detaching it it willbe found exceptionally convenient for attachment of draft devices of anykind or the direct securement thereto of links, chains, and the like,and in view of the simplicity of the device it can be manufactured andsold at a small cost.

Having thus described the invention, what is claimed as new is 1. Aclevis having ahead with slots arranged in vertical alinement therein,and ablock for attaching purposes adapted to be interchangeably mountedin either of the slots.

2. A clevis having a head with verticallyalined slots, a block forattaching purposes interchangeably mounted in either of the slots, and abolt removably mounted in the head and engaging the block.

3. A clevis having a head with verticallyalined slots, a block adaptedto be interchangeably mounted in relation to said slots, and having anattaching device applied thereto, the upper and lower ends of said blockhaving at one side and in opposite positions being provided withflanges, and means for removably securing the slots in the block.

4. A clevis comprising a pair of parallel bars for embracing a beam, avertical brace connecting said bars near the outer ends thereof, a spurdisposed on said brace and adapted to engage said beam, an intermediatepartitionbar projecting outwardly from the brace in a line parallel withthe extended ends of the beam-embracing bars, and a block adapted to beinterchangeably mounted in the openings or slots formed by theseextended ends and the partition-bar.

5. A clevis "comprising two parallel bars adapted to embrace a beam, avertical brace connecting said bars near the outer end thereof, anintermediate bar projecting outwardly from the brace in a line parallelwith the extended ends of the beam-embracing bars, and forming slots, ablock adapted to be mounted in one of said slots, and a bolt extendingthrough the outer ends of said bars and through said block, and aclevis-loop connected with said block.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

YVILLIAM M. GRISWOLD.
